What is an important safety feature to check during the exterior inspection?

The condition and visibility of all lights is a crucial safety feature to check during the exterior inspection. Adequate lighting is essential for the safe operation of a vehicle, especially in low-light conditions or during inclement weather. Properly functioning lights, including headlights, taillights, turn signals, and hazard lights, ensure that the driver can see the road and that other road users can see the vehicle. This visibility helps prevent accidents by communicating the vehicle's intentions, such as turning or stopping, to other drivers and pedestrians.

In contrast, while the alignment of the mirrors, functionality of the emergency exit, and presence of safety equipment are all significant safety aspects to examine, they do not directly affect the immediate visibility and communication of the vehicle on the road during operation. Therefore, ensuring that all lights are in good working order is foundational for safe driving.
